Summary: The manufacturer makes a fantastic bag, and it was shipped quickly. Nice job. It appears that the product described on the site for this product number is not the bag that was delivered to me. Perhaps it is and this site simply needs to update their product description. Bag is okay mainly because my expectations were not met. I used to have one of the 15 inch X-Brace bags from the same manufacturer, like that described on the site with the insert.
Summary: I've just had mine for a little while and had read the reviews before purchasing. Strap is one piece with the jell shoulder pad slid onto it (this ain't gonna break now how), my Gateway 17'' P-7805u FX laptop fits like a glove in the padded area with room for all other gear including my Zalman Notebook Cooler ZM-NC2000, mouse, power surge protector, etc.
Summary: I really like the removable laptop case. It has shoulder strap hooks, so I can carry the laptop insert just like a small briefcase. This is nice for when I know all I will need is the laptop for a few hours.
